Description

A water regulating device

technical field

The invention relates to the field of water treatment, in particular to a water volume regulating device.

Background technique

Water tap is the popular appellation of water valve, is used for controlling the size switch of water flow, and water tap is installed in every household. As water pollution becomes more and more serious, people need more reliable water quality to protect their health. Therefore, many families will install filters on the faucets, and filter the tap water through the filters before using them. In existing faucets, the filter screen is generally installed at the water outlet of the faucet, and using the existing faucet to filter tap water has the following disadvantages:

(1) The filter screen filters the tap water for a long time, and a lot of impurities will accumulate on the filter screen. Generally, the existing faucet will keep the tap water flowing through the filter screen. At this time, it is difficult to remove the filter screen from the faucet for cleaning. If it is disassembled, the impurities on the filter will pollute the tap water and endanger people's health;

(2) The filter needs to withstand the pressure from tap water, but limited by environmental factors, the pressure of tap water in the faucet will change. If the pressure of tap water in the faucet is too high, the filter cannot withstand the pressure from tap water and will be washed out filter, causing damage to the filter.

A first spring 111 is installed in the first cavity 11. A blind hole 51 (as shown in FIG. 8 ) is formed at the bottom end of the cylindrical plug 5. A protrusion is formed on the bottom wall of the first cavity 11. The first spring One end of 111 is sleeved on the protruding piece and against the bottom wall of the first cavity 11, the other end of the first spring 111 is inserted into the blind hole 51 and against the columnar plug 5, under the elastic force of the first spring 111, the columnar The top end of the plug 5 is inserted into the first through hole 21 , resulting in fluid isolation between the first cavity 11 and the second cavity 12 , so that the water in the first cavity 11 no longer flows into the second cavity 12 .

In this embodiment, the first through hole 21 is circular. In other embodiments, the first through hole 21 may be oblong or elliptical.

The second spacer 3 is installed between the second cavity 12 and the third cavity 13, the second spacer 3 is formed with a second through hole 31, and the second cavity 12 passes through the second through hole 31 and the third cavity Body 13 achieves fluid communication. The water in the second cavity 12 can flow into the third cavity 13 through the second through hole 31 .

There is an opening formed on the top of the housing, and the adjusting member 7 is inserted into the opening. The bottom of the adjusting member 7 is formed with a slope protrusion 71 (as shown in FIG. 5 ), and the top of the tapered needle 4 is formed with an adjusting disc 41. It is formed on the lower surface of the adjustment disc 41 , and the upper surface of the adjustment disc 41 is formed with a columnar protrusion 411 (as shown in FIG. 4 ), wherein the slope protrusion 71 and the columnar protrusion 411 interfere with each other. Turn the adjustment member 7 clockwise, the columnar protrusion 411 moves vertically downward under the pressure of the slope protrusion 71, thereby prompting the adjustment disc 41 to drive the tapered needle 4 to move vertically downward, prompting the tapered needle 4 to be inserted In the second through hole 31, by controlling the clockwise rotation range of the adjustment member 7, the depth of the tapered needle 4 inserted into the second through hole 31 can be controlled, that is, the flow rate of water flowing through the second through hole 31 can be controlled, and That is, the water pressure in the third cavity 13 in the water volume regulating device can be adjusted to prevent the water pressure in the third cavity 13 from being too high.

In this embodiment, the number of the tapered needle 4 and the number of the second through holes 31 are both six. In other embodiments, the number of the tapered needle 4 and the second through hole 31 can be changed according to the actual situation. As long as the tapered needle 4 is inserted into the second through hole 31 , the water pressure in the third cavity 13 in the water volume regulating device can be adjusted to prevent the water pressure in the third cavity 13 from being too high.

When the adjusting member 7 needs to be disassembled from the opening of the housing, the housing around the opening of the fixing nut 8 is separated, and the The adjusting part 7 is disassembled from the opening of the housing, which is convenient and quick.

A fifth through hole 73 is formed on the adjusting part 7, and a fourth through hole is formed on the adjusting disc 41. One end of the pressing part 6 is against the top of the columnar plug part 5, and the other end of the pressing part 6 passes through the fifth through hole 73 in turn. and the fourth through hole and extend to the outside of the housing. When the pressing part 6 is pressed down under the action of an external force, the columnar plug 5 will be disengaged from the first through hole 21, so that the first cavity 11 and the second cavity Realize the fluid communication between body 12, can make the water in the first cavity 11 flow into the second cavity 12; move upward, so that the top end of the cylindrical plug 5 is inserted into the first through hole 21, so that fluid isolation is realized between the first cavity 11 and the second cavity 12, so that the water in the first cavity 11 no longer flows into the second cavity. cavity 12.

The third cavity 13 is in fluid communication with the water outlet 15. The third cavity 13 is formed with a third through hole 131 (as shown in FIG. 2 ), and the filter screen 9 is inserted into the third through hole 131, so that the filter screen 9 is located in the third through hole 131. At the junction of the three chamber body 13 and the water outlet 15, the sealing cover is threadedly connected with the third through hole 131. When the filter screen 9 needs to be cleaned, the sealing cover is removed from the third through hole 131, and then the filter screen 9 is cleaned. After cleaning, insert the filter screen 9 from the third through hole 131, and then screw the sealing cover to the third through hole 131, which is convenient and quick.

When using the present invention, water enters the first cavity 11 from the water inlet 14, and presses the pressing part 6 with an external force.
